When you’re rebuilding an engine and the crankshaft journals are worn beyond standard limits, you need bearings sized to match the machine work. This main bearing set gives you exactly what your machinist ordered—oversized bearings that create the proper oil clearances for long engine life. Nothing’s worse than putting in all that work just to have bearing problems down the road.
What You’re Getting
- Complete set with center, front, and rear main bearings for one engine
- Precision .010 inch oversize dimensions to match turned crankshaft journals
- Quality construction that meets OEM specifications for durability
- Direct replacement that installs just like the originals
- Includes everything needed for proper main bearing installation
Built for Real Farm Work
This bearing set fits Ford engines including 134 CID gas, 172 CID gas, and 172 diesel versions that power a wide range of classic Ford tractors. These are the workhorses that still earn their keep on farms today—pulling implements, running PTOs, and handling the daily grind of agricultural work.
Made to Last
Main bearings are the foundation of your engine’s bottom end, supporting the crankshaft through thousands of hours of operation. These bearings use quality materials and precise manufacturing to handle the loads and stresses of farm work, from pulling heavy equipment to running at governed RPM all day long.
Good to Know
These are oversized bearings designed for crankshafts that have been turned .010 inch undersize to clean up wear or damage. Make sure your machine work matches this bearing size—using the wrong oversize will give you either too much or too little oil clearance. Your engine rebuilder will know the proper clearances, but it’s always good to double-check the measurements before assembly.
